The Fiberglass pool is a fiberglass shell that is carried to your location. A hole is dug similarly to the vinyl inground pool and then the shell is lowered in to place. Fiberglass pools usually have a similar warranty to the vinyl inground pools and are also very popular with residential pool builders.

They generally cost 5000-10000 more for a similar sized pool then the vinyl inground. The greatest advantage is that they do not have a liner that needs to be replaced every decade. When selecting a fiberglass builder you should be sure he has great experience as a fiberglass pool can be easy to set wrong and have trouble with cracks later in life if done wrong.
